基于DSP和1553B总线的嵌入式系统的设计与实现
|
摘要
本文主要从硬件和软件设计方面阐述了基于DSP和1553B总线接口的嵌入式系统的设计与实现。首先阐述了系统的硬件设计方案,包括DSP、CPLD、1553B总线接口、A/D、D/A、开关量输入/输出、定时器、脉冲输入和外部中断的实现;然后介绍了CPLD内部逻辑的设计过程;接下来详细叙述了1553B总线RT模式的实现和测试过程;最后对系统其他模块的软件设计与实现进行了研究。
本系统将DSP强大的数据处理能力、CPLD的灵活性和1553B总线的分布处理、集中控制和实时响应的特点相结合,具有系统集成度高、处理速度快以及较强的通用性和可扩展性。该设计方案为基于DSP的嵌入式系统和1553B总线接口适配器的深入研究,提供了一种通用可行的解决方案。
In this paper, design and implementation of embedded system based on DSP and 1553B bus is elaborated from two aspects, namely, hardware system design and software program design.Firstly,the scheme of system hardware design is elaborated, including DSP, CPLD,1553B bus interface,A/D,D/A,switch input/output, timer, impluse and external interrupts input. Secondly, the design process of the internal logic of CPLD is introduced. Thirdly, the realization and process of test of 1553B bus as RT mode have been descripted in detail. Finally the design and implementation of other modules of the system software is studied.
Combining the advantages of the powerful data processing of DSP, the flexibility of CPLD and the characters of 1553B bus, which are distributed processing, Centralized Control and Real-Time Response, the merits of this system are high system integration, high processing speed, and high versatility and scalability. In this design, a general solution is supplied, which is for further study on embedded system based on DSP and 1553B bus adapter.
